It is to be understood that such discussion and description is not to unduly limit the scope of the invention.

Referring to the drawings, and in particularly to FIGS. l, 4 and 5, the physical therapy apparatus for'persons at bedrest, generally'indicated -by a numeral ll, is shownhaving base member 12 secured to end post 13 of bed 14 by mounting means 16. Bicycle-type exerciser machine 17 is secured to the inner surface of base member 12 so that bicycle-type exerciser images ofeach other and are in a facing relationship with each l other as shown.

machine 17 is positioned within bed 14 as shown thusenabling persons at bedrest to operate the same. Coordination restoring means 18, which will be discussed in detail hereinafter is positioned at the upwardly-extending edge portion of base member l2 for storing coordination restoring means I8 when the same is not in use. A pair of target members I9 are positioned at the upwardly extending corner portions-of base member I2 and a pair of pulley means 2l are likewise secured to the upwardly extending portion of base member 12 and positioned in a parallel spaced relationship with each other.

Base member l2 is provided with an opening 22 in the upwardly extending portion thereof and rod member 23 is secured to the upper edge of base member l2 by any suitable means such iis-clamp members 24 thus securing rod member 23 across the top portion of opening 22. A plurality of hook members 26 (see FIG. l) are slidably positioned on rod member 23 and hook members 26 are employed to hold and thus store variousobjects used to entertain persons atbedrest and employed in the exercising of such persons, such as weights, darts, bowling pins, sandbags and the like.

Bicycle-type exerciser machine 17 is provided with forward leg members 27 and'28 each of which is positioned within clamp member 29 at one end. Clamp member 29 is then affixed to base member l2 adjacent opening 22 by any suitable means, such as screws, bolts and the like thus rigidly securing clamp member 29 and the forward leg members 27 and 28 to base member l2. Forward leg members 27 a'nd 28 converge at their other end as shown. Forward leg members 27 and 28 are constructed to be mirror images of each other and are in a facing relationship with each other. A body member 3l, here shown as a substantially Z-shaped member, is secured -at one end to converging end portion of forward leg members 27 and 28 by connecting member 32 and body member 31 is positioned so that its other end extends upwardly so that seat member 33 positioned upon rod member 34 can be slidably positionedv within body member 3l as shown, and then secured in place as by any suitable means such as a bolt, clamp and the like (not shown). One end portion of each of rearward leg members 36and 37 are positioned within clamp member 29 and clamp member 29`is then secured to base member l2 by any suitable means such as screws, bolts, and the like, thus securing rearward leg members 36 and 37 to base member l2. The other end of rearward legmembers 36 and 37 converge until the end portions thereof are adjacent and parallel body member 3l. The upwardly extending end portions ofrearward leg members 36 and 37 are fixably secured'to body-member 3l by any suitable means such as bolt members 38. Rearward leg members 36 and 37 are likewise constructed to be mirror Handlebar means are provided which consist of a handle bar support member 39 which is pivotallyzsecured to connecting means 32 by pin element 41 and two handle members, 42 and 43, which are of substantially L-shaped structure.fas shown, and which are secured to the upwardly extending end portion of handlebar support member 39 b yrany suitable means such as bolts 44. Handle members 42 ands43are covered with collar members 46 and 47, respectively,'.a rlid collar members 46 and 47 are preferably made of a plastic or rubbery material thus enabling the person to readily grasp. handle members 42 and 43 without the persons hands slipping thereon. Linkage means. which will be discussed hereinafter operatively connect the handlebar means and pedal means 52 so that they operate together at all'times. The downwardly extending end portion of handlebar support member 39 is secured to one end of linkage member 48. The other end of linkage member 48 is, in turn, pivotally connected to one end of a second linkage member 49.` The other end of second linkage member 49 is then secured to crank arm 51 of pedal means 52. As is readily apparent from the drawings, opening 22 within base member l2 is necessary invorder to allow unrestricted movement of first and second linkage members 48 and 49 when handlebar support member 39 and pedal means 52 of the bicycle-type exerciser machine 17 are moved.

Pedal means 52 is provided with shaft 53 rotatably mounted onbody member 31 in any suitable manner, such as by the use of pillow block 54. Crank arms 51 and S6 each haveone end portion thereof secured to opposite end portions of shaft 53 and are secured there to so as to extend from shaft 53 180 apart. Foot pedals57 and 58 are secured to the other end portion of crank arms S6 and 5l, respectively. Pedals 57 and 58 can be ofthe conventional bicycle-type pedal but are modified (see FIG. '6) to have coupling means affixed to the lowerI surface of pedals 58 and 59 so that the foot portion of a person positioned within a suit for circulation of hydraulic fluid around the body; such as disclosed in my copending U.S. Pat. application entitled SUIT FOR CIRCULATION OF FLUID AROUND BODY, Ser. No. 689,626, filed Dec. ll, |967, now U.S. Pat. No. 3,521,621, can have their feet secured to pedals 57 and 58. A support member S9 is pivotally connected to pedals 57 and 58 and support members 59 are provided with strap members 61, or any other suitable connecting means, so that the persons legs can be secured to and supported on pedal members 57 and 58. By securing the person's legs to the supports the person is provided with a sense of security even thoughthe person has no control over the muscles in the leg.

Resilient means, such as spring elements 62 are secured at one end to downwardly extending end portion of handlebar support member 39, as shown, and the other end of spring elements 62 are secured to body member 31 of bicycle-type exercising machine 17 at a point adjacent but in front of the pillow block 54.` As is readily apparent, pedals 57 and 58 and handlebar support member 39 cooperate together to move at all times and spring elements 62 add tension to the same so that a person can readily improve muscle tone and coordination by employing bicycle-type exerciser machine 17. The force required to operate pedals 57 and 58 and handlebar support member 3l canreadily be varied by varying the tension on spring elements 62.

Physical therapy apparatus 11 is further provided with a pair of pulley means 2l, each of which are provided with a bracket 63 securely fixed to the inner surface of base member I2. A pulley wheel 64 is then rotatably positioned'within bracket 63 by pin element 66 and belt member 67 is yentrained over pulley wheels 64. Pulley wheels 64 and thus belt'member 67 are employed lto hang sandbags, weights," and the like, thereon so that the patient within a bed can use same to improve strength within various parts of they body bymoving the tient by the throwing of the dart (not shown) at dart targets 19,and, at the same time, entertain persons at bedrest thus preventing boredom so that their willingness to improve can be maintained atthe desired high level, and develop aim and direction.

'I`wo support members 68 and 69 are each provided with a Y body central portion 71 and having end portions 72 and 73 positioned at'substantially 90 with respect to central portion 71'and substantially parallel to each other. Central portion 7l of support members 68 and 69 is slidably positioned parallel to base member 12 by eyelet members 74 and 76 so that support members 68 and 69 can be slidably raised and then rotated so as to be positioned in front of handle members 42 and 43 of handlebar support member 39. As is readily apparent when support members 68 and 69 are raised and rotated as discussed immediately above, end portion 73 of supportmembers 68 and 69 is forced against base member l2 thus maintaining coordination restoring means l8 which is secured to end portion 72 of support members 68 and 69 Ain a stable position infront of the patient lying in bed 14, thus affording the patient access to coordination restoring means 18.

Referring now to FIG. 2, mounting means 16 for mounting base member 12 to end post 13 of bed 14 is shown as U-bolt member 77 positioned over the top rung of end post 13. U-

and thus creating fear within the mind of the patient. Rearf ward leg member 37 and body member 31'of bicycle-type machine 17 are likewise shown in their position'with respect to hed 14. As is readily apparent, by the positioning bicycletype apparatus 17 as shown the apparatus is firmly maintained upon base member l2 and maintained in a parallel spaced relationship butin a close proximity with bed '14.

Referring now `to FIGS. 3 and 4 coordination restoring means 18 is shown having attachment base member 81 positioned upon and secured to end portion 72 of support members 68 and 69. Attachment base member 8l is provided with a plurality of openings 82, 83,84, 86 and 87 therein and a plurality of rib members 88,89, 91, 92 and 93positioned around the circumference of the openings 82,- 83, 84, 86 and 87. Openings 82. 83, 86 and 87 are each provided with threads vtherein (not shown) which mate with correspondingthreads 94 of screw-type block members 96, 97, 98, and 99. Rib members 88, 89, 92 and 93 are likewise provided with mating threadstnot shown). As is readily apparent the various sizes of block members 96, 97, 98 and 99 and openings 82, 83, 86.and 87 vary thus providing variation in coordination-restoring means 1 8. Block members 96, 97, 98 and 99 are preferably formed of a light` durable plastic material and are provided with oversized threads so that the person does not expend excessive energy in handling the block members and also to prevent injury to the Iperson if they should drop one of the block membersAOpening 84 in attachment base member 81 preferably differs from the above-mentioned opening in base member 8l in that opening 84 is a friction-type opening and friction-type block member 101 is adapted so as to be capable of being inserted within opening 84. By employing the threaded and friction-type block member the patientis able to restore coordination within his arms and hands, and, at the same time, is afforded a variety of physical therapy treatment so that the patient does not become bored and thus maintain a good attitude which is necessary if the person is to recover from their physical injuries.

In order to provide stability to coordination restoring at tachment means 18 when the same is in a lowered position for access by a person at bedrest a hook means 102 is pivotally connected at one end to attachment base member 81 by swivel means 104 as shown in FIG. 3. The other end portion prising supportmember 59 and straps 61, positioned thereon. v Support member'59 and straps 61 are very important in that a person having no control or coordinationoverithe feet and legs can have their leg secured to thepedal thus` enabling the person to use the apparatus. Further, a coupling means, such as plate element 106, is affixed to thlower surface of pedal 58 and pedal 57 (not shown). Plate element 106 is provided with two openingstherein which are aligned and communicate with openings'in pedal 58 and pedal 57 (not shown) so that connecting means, su'ch as disclosed in the copending U.S. Pat. application entitled SUIT `FOR CIRCULATION OF FLUID AROUND BODY, Ser. No. 689,626, filed Dec. II` 1967, can be inserted therethrough thus securing the sole portion of the'above-mentioned suit and thus the persons feet to the pedals of thevbicycle-type apparatus.

Referring-nowV to FIGS. 7, 8, and 9, a second preferred specific embodiment of the physical therapy apparatus of the invention is shown, In order to more fully understand ythe operation of the-apparatus as depicted in FIGS. 7, 8, and 9 wherein a drive and operating means is provided for bicycle'- type exerciser machine 17 described in FIGS. 1, 4, and 5, the entire apparatus will be described in order to provide a clearer and more descriptive understanding of the embodiment shown in FIGS. 7, 8, and 9.

Physical therapy apparatus for persons atvb'edrest, generally indicated by numeral l1, is shown having the base Amember 12 secured to end post 13 of bed 14 by mounting means 16. Bicycle-type exerciser machine 17 is secured to thenner surface of base member 12 so that bicycle-type exerciser machine 17 is positioned within bed 14 asshown thus enabling persons at bedrest to operate the same. Coordination restoring means 18,

which was discussed in detail with reference to FIGS. 3 and 4, is positioned at the upwardly extending edge portion of base member 1.2 for storing coordination restoring means 18 when the same is not in use. Target. members 19 and pulley means 21 are likewise secured to the upwardly extending portion of base member l2 and positioned so that the persons at bedrest have easy access to the same thus enabling them to employ the same in physical therapy treatment as previously described.

Base member l2 is provided with an opening 22 in the upwardly extending portion thereof and rod member 23 is secured to the upper edge of base member 12 by any suitable means such as clamp members 24 thus securing rod member 23 across the top portion of opening 22. A plurality of hook members 26 are slidably positioned on rod member 23 and hook members 26 are employed to hold and thus store various objects used to entertain the persons at bedrest and employed in the exercising of such persons, such as weights, darts, bowling pins, sandbags, and the like.

Bicycle-type exerciser machine 17 is provided with forward leg members 27 and 28, each of which is positionedwithin clamp member 29 at one end. Clamp member 29 is then'affixed to base member 12 adjacent opening 22 by any suitable means, such as screws, bolts andthe like, thus rigidly securing clamp member 29 and thus forward leg members 27 and 28 to base member 12. Forward leg members 27 and 28 converge at theA other end as shown and are constructed to be mirror images of'each other and are in a facing'relationship with each other. A body member 31, here shown as a substantially Z- shaped member, is secured at one end to converging end portions of forward leg members 27 and 28V by connecting member 32 and body member 31 is positioned so that its other end extends upwardly so that seat member 33 positioned upon rod member 34 can be slidably positioned within body members 31 as shown, and then secured in place by any suitable means such as a bolt, clamp, and the like. On'e end portion of each of the rearward leg members 36- and 37 is positioned within clamp member 29 and clamp member 29 is then secured to base member 12 by any suitable means such as screws, bolts, and the like, thus securing rearward leg members 36 and 37 to base member 12. The other end portion of rearward leg members 36 and 37 converge until the end portions thereof are adjacent and parallel body member 31. The upwardly extending end portions of rearward leg members 36 and 37 are fixably secured to body member 31 by any suitable means such as bolt members 38. Rearward leg members 36 and 37 are likewise constructed to be mirror images of each other and are in-a facing relationship with each other as shown.

Handlebar means are provided which consist ofa handlebar support member 39 which is pivotally secured to connecting means 32 by pin element 41 and two handle members, 42 and 43, which are of a substantially L-shaped structure as shown, and which are secured tothe upwardly extending end portion of handlebar support member 39 by any suitable means such as bolts 44. Handle members 42 and 43 are each covered with collar members 46 and 47. respectively, and collar members 46 and 47 are preferably made of a plastic or rubberlike material thus preventing the persons hands from slipping from handle members 42 and 43. The downwardly extending end portion of handlebar support member 39 is secured to one end of first linkage member 48. The other end of first linkage member 48 is, in turn, pivotally connected to one end of a second linkage member 49. The other end of second linkage member 49 is then secured to crank arm 51 of pedal means 52. As is readily apparent from the drawings, opening 22 within base member 12 is necessary in order to allow unrestricted movement of first linkage member 48 and second linkage member 49 when handlebar support member 39 and pedal means 52 of bicycle-type exerciser machine 17 are moved.

Pedal means 52 is provided with shaft 53 rotatably mounted on body member 31 by any suitable means, such as by the use of pillow block 54. Crank arms 51 and 56 have one end portion thereof secured to opposite end portions of shaft 53 and are secured thereto so as to extend from shaft 53, 180 apart. Foot pedals 57 and 58 are secured to the other end portion of crank arms 56 and 51, respectively. Pedals 57 and 58 can be of the conventional bicycle-type pedal but are modified as shown in FIG. 6 to have a connecting means, such as plate ele-.

ment 106 positioned thereon as previously discussed. Plate element 106 is especially desirable so that persons employing a suit for circulation of fluid around the body, such as disclosed in my copending U.S. Pat. application entitled SUIT FOR CIRCULATION OF FLUID AROUND BODY, Ser. No. 689.626, filed Dec. 1l, 1967, can have their feet secured to the pedals 57 and S8 by connecting means provided on the sole portion of the suit above mentioned. A support member 59 is pivotally connected to each of pedals S7 and 58 and each support member 59 is provided with strap 61, or any other suitable connecting means, so that the persons legs can be secured and supported from vpedal members 57 and S8. By securing the persons legs to the support members, the person is provided with a sense ofsccurity even though the person has no control over thc muscles in the legs.

A resilient means, such as the two spring elements 62 are secured at one end tol downwardly extending end'portion of handle bar support member 39, as shown, and the other end of spring members 62 are secured to body member 31 of bicycletype exercising machine 17 at a point adjacent but in front of pillow block 54. As is readily apparent, pedals 57 and S8 and handlebar support member 39 cooperate together at all times and springs 62 add tension to the same so that the person can readily improve muscle tone and coordination by employing bicycle-type machine 17 previously described. However, the force required to operate pedals 57 and 58 and the handlebar support member 39 is many times too great a force to be exerted by a person at bedrest. When such a case is encountered a drive and operating means 105 is provided and is mounted in operating relationship with pedal means 52 of bicycle-type apparatus 17 sothat the pedal means 52 and handlebar support member 39 can be moved for the patient by a power means, but, at the same time providing the persons at bedrest with the desired exercise of the muscles.

Suitable power means, such as electric motor 107 is mounted on base member 12 in any suitable manner, such as mounting bolts 108. Motor 107 preferably is positioned on the lower portion of base 12 and near rearward leg member 36 as shown in FIG. 7. Motor 107 preferably has two or more speeds which may be varied by a variable speed control means such as switch 109 mounted on handle member 43 or the speed of" motor 107 can be varied by using rheostat 111. As is readilyapparent the speed of motor 107 c an be varied by employing, in combination, both switch 109 and rheostat 111. l

Referring now to FIGS. 8 and 9 drive and operating means is shown in detail. Pulley 112 is mounted on shaft 113 of electric motor 107. A second shaft 114 is mounted for rotation on base 12in any suitable manner, such as pillow blocks 116. A second pulley 117 is affixed to shaft 114 to turn therewith, Pulley` 117 receives a V-belt 118 which is connected to first pulley 112 on electric motor 107. A third pulley 119 is also affixed to shaft 114 of fourth pulley 121 as affixed to crank arm 56vof pedal means S2 and positioned adjacent pillow block 54 as shown. Fourth pulley 121 receives a second V-belt 122 which is connected to third pulley 119 on shaft 114. As is readily` apparent, the four pulleys 112. 117,119 and 121 andthe two V-belts 118 and 122 cooperate so that as pulleys 112-and shafts 113 are driven by electric motor 107, shaft 114 is also driven thus driving pulleys 117, 119, and 121 thereby rotating pedal means 52 and thus oscillating handlebar support member 39 at the desired rate,

Electric wires (not shown) extend from electric motor 107 through the hollow tubular body structure of bicycle-type machine 17 to switch 109 so that switch 109 is in electrical contact with motor 107. As is readily apparent, the apparatus shown in FIGS. 7, 8, and 9 can be operated without the need for external power. However, by utilizing an electric motor to drive pedal means 52 and oscillate handlebar support member 39 a person havin-g absolutely no control over the'muscles in their arms or legs can utilize the apparatus while remaining in bed and thus allow persons having such a disability to exercise their muscles and thus prevent further deterioration of the muscles.

While'the invention has been described in connection with specific embodiments, it will be evident to those skilled in the art that various'modifications of this invention can be made or followed in light of this discussion and description, without departing from the spirit ofthe disclosure or the scope of the claims.
